Teresa Clements, also of Napier, said as someone who has been in domestic violence situations before she attended the march to make a stand against these recent public acts of violence towards women.
"It's not nice for women to be treated in this manner."
Yvonne Faulkner, of Taradale, said she knew two of the attack victims and marched in support of them.
"I want to make our streets safer."
